H. ACKERMAN WIRE TYING TOOL Dec. 30,1952

Filed March 4, 1950 flarzg/ QCZZZZE BY M i Patented Dec. 30, 1952 UNITED STATES PATENT I OFFICE 2 Claims.

This invention relates to wire tying devices and has as its primary object the provision of a wire tying tool that is simple, sturdy, and easy to use, yet capable of drawing relatively heavy and stiff wire sufiiciently taut so that it is not only useful for binding boxes, crates, shipping cartons, etc., but may be used for applying wire hose clamps and various other permanent or semipermanent wire fastenings.

It is a further object of the invention to provide a tool of design and construction suited to the application of a binding comprising either a single strand or a double strand of wire.

Other objects of the invention are to provide a small, conveniently handled, pocket-size tool adapted to be used as a hand tool or supported in a vice for use as a bench tool.

Further objects are to provide a tool having the functional characteristics outlined above, yet of such construction as to be well suited to inexpensive mass production methods of manufacture, and practically indestructible in use.

A present preferred embodiment of the invention is illustrated in the drawings of this application, wherein:

Figure l is a front elevational view of the tool, showing the manner in which it is used in the application of a double strand wire hose clamp;

Figure 2 is a fragmental detail sectional View taken substantially on the plane of the line 2-2 of Figure 1;

Figure 3 is a fragmental view similar to Figure 1, showing the position the parts assume as the binding is tightened;

Figure 4 is a front elevational view of a double strand wire binding as formed by the present teachings, showing the binding applied as a hose clamp;

Figure 5 is a fragmental perspective View showing the manner in which the tool is employed for tightening a single strand binding; and

Figure 6 is a side elevational view of a single strand binding employed as a hose clamp.

The tool consists of a body portion H) which may be a single, integral piece of cast metal and is provided with a transverse bore I 1, into which a rotary shaft I2 is journaled. The shaft 12 has an annular groove l3 (Figure 3) into which a machine screw l4 projects to retain the shaft in the bore, but permits unrestricted rotary movement. The outer end of the shaft 12 carries a hand lever in the form of a cross pin [5 projecting through an opening IS in the shaft and knurled at the ends I! and [8 so that it will retain itself in position. The inner end of the shaft constitutes an arbor portion on which the wire is Wound, and is accordingly provided with a transverse slot [9 through which the wire may be passed, although other means may be em ployed to secure the wire to the arbor.

The body of the tool includes an offset neck 2! terminating in a head portion 22 adjacent the arbor of the shaft and, as shown, the head is pierced by two parallel bores 23 extending substantially at right angles to the shaft 12, so that the wire may be passed through the bores and threaded through the slot 19 of the arbor shaft. The tool also includes a handle portion which is preferably opposite the head portion 212 and consists of a relatively broad, smoothly rounded palm grip plate 26 having a curved end surface 21 extending somewhat laterally from the body to a position on the opposite side of the slot Hi from the head portion 22. As illustrated, the tool is also provided with a square stud 28 extending outwardly from one of its surfaces and adapted to be clamped in a vise to support the tool when it is desired to use it is a stationary bench mount.

The manner in which the tool is employed in applying a double strand binding will be apparent from viewing Figures 1 and 2, which show the initial steps of applying the binding, taken with Figure 3 showing the manner in which the wire is tightened, and Figure 4 which illustrates the completed binding. From these figures it will be clear that a length of wire sufficient to encircle the article (which is, in this instance, a length of rubber hose 3| fitted over a threaded nipple 32) will be doubled upon itself by reverse bend 33 and then wrapped around the hose by passing the two strands 34 and 35 of the Wire through the loop 33, as shown in Figures 1 and 2. The free ends 34 and 35 of the wire are slipped through the bores 23 of the tool head and through the slot IQ of the winding arbor [2. The wire is then drawn taut by manually rotating the arbor by the cross pin E5 in such a manner that the wire strands 34 and 35 form a coil 36 on the arbor. The wire is then doubled back to form locking bends 31 (Figure l) by applying the palm of a hand to the gri portion 26 of the tool and doubling it back against the work. The wire strands may be severed in any convenient manner, and when severed will leave a binding or hose clamp as 11- lustrated in Figure 4.

In the event that a single strand binding is desired, the wire is applied as in Figure 5, by forming a loop 40 from which the free ends 38 of the wire are drawn through the bores 23 and passed through the slot I9 of the arbor in.

suited to the application of either single or double I strand bindings as desired. It provides adequate leverage to permit even comparatively large and stiif wires to be drawn taut by hand without the need of power devices, and provides a convenient arrangement for removing the end strands of wire from the device after the binding has been completed, since when the ends of the wire binding are severed, the free ends still attached to the coil 36 may be drawn inwardly until they clear the bores 23 of the head and the entire-coil then lifted from the slotted portion of the arbor and discarded.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:

1. In a wire tying tool, in combination, a tool body comprising a single integral elongated metal shape having a transverse bore therethrough, with an oifset head portion at one end and a handle portion having a relatively broad and smooth flared palm grip at the opposite end and being offset in the same direction as said head and substantially to the same extent, portions of said palm grip and said head being in the same horizontal and vertical planes whereby a maximum amount of leverage may be applied without twisting movement of the tool during wire tightening movement thereof; a shaft extending 40 through and rotatably journaled in said bore,

with a hand lever extending laterally from the shaft at one end thereof, and a transverse slot in the shaft adjacent the offset head portion to provide a wire tightening arbor said slot being in substantial alignment with said portions of said palm grip and said head; together with means to retain the shaft in the bore of the body, and a pair of parallel, spaced-apart wire guide apertures in the head portion adjacent said arbor.

2. In a wire tying tool, in combination, a tool body comprising a single integral elongated metal shape having a transverse bore therethrough, with an offset head portion at one end and a handle portion having a relatively broad and smooth flared palm grip at the opposite end and being offset in the same direction as said head and substantially to the same extent, portions of said palm grip and said head being in the same horizontal and vertical planes whereby a maximum amount of leverage may be applied without twisting movement of the tool during wire tightening movement thereof; a shaft extending through and rotatably journaled in said bore, with a hand lever extending laterally from the shaft at one end thereof, and a transverse slot in the shaft adjacent the oifset head portion to provide a wire tightening arbor said slot being in substantial alignment with said portions of said palm grip and said head; together with at least one wire guide aperture in the head portion adjacent said arbor.
